    Phoronix: Wine Patches Coming To Allow UMIP Emulation - Works Around Issues For Ryzen 3000

    Coming up this weekend with the Linux 5.4 kernel is emulation/spoofing of the SGDT/SIDT/SMSW instructions around UMIP for allowing newer 64-bit Windows games to run on Wine and Steam Play (Proton). With newer CPUs like the AMD Ryzen 3000 series that support UMIP, these instructions are not allowed to run in user-space with Wine due to UMIP. So while the first stable kernel release is about to land with this support, some Wine-based emulation not contingent on the kernel patches is also in the works...

      So Codeweavers has to write code for the WINE Windows emulator on Linux because code developers on Windows do sloppy things like executing privleged CPU commands in user space.

      No wonder Windows is riddled with malware and virii... Windows users have to run stuff in Administrator mode just so they can play their gam3z. /facepalm

      That's the conclusion I came to after reading this link in the article:

      I guess those that CAN code choose to write software for Linux & MacOS while those that CAN'T code are relegated to writing Windows & smartphone software. /sarcasm

        Yeah, Windows "security" is just dialog boxes slapped over a 90s kernel they stole from IBM, news at 11.
